SHOWER PIPE.

Application sied To all whom il; may conce/rn:

Be it known that I, JAMES T. MURPHY, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Showerl Pipes, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, Lforming a part of this specification.

Various kinds of paper making machinery embody shower pipes for cleaning felts, rolls, strainer drums, drum molds, etc. '.lhese strainer pipes comprise among other things a pipe having a plurality of comlmratively small openings through which water or steam. is discharged upon the element to be cleaned. These openings frequently become clogged with dirt kof various kinds and particularly is this true where the same water is used over and over again. Many means have heretofore been proposed for cleaning these openings and one of the objects of my invention is to simplify the means for cleaning the openings of shower pipes and the operation of cleaning them.

Another object of my invention is to provide means whereby these openings may be cleaned and the dirt dislodged therefrom flushed from one end of the pipe so as not to be discharged upon the element which is supplied with water from the shower pipe.

A further object of my invention is to provide means for supplying hot water under pressure to the shower pipe for cleaning purposes. This is particularly desirable where the water used in the shower pipe carries parafiin or other soluble matter in solution or suspension. Such materials are very difficult to dislodge from a shower pipe, but by supplying hot water thereto, they can be dissolved or melted and carried away.

A still further object of my invention is to provide means for supplying steam under pressure to the shower pipe and means for insuring this steam passing out through the openings of the shower pipe southat the shower pipe can be used for cleaning drum molds, etc.

A final object of my invention is to provide a shower pipe of the type referred to which is simple in construction, easy to operate and economical to manufacture.

Other objects of my invention will appear as this description progresses, reference October 23, 1922. Serial No. 596,271.

being had to the accompanying drawings, in which `Figure 1 is a plan view of my improved shower pipe;

Figure 2 is a side elevation thereof;

n Figure 3 is a transverse section taken on the line3-3 of Figure 1; and

Figure 4j is an enlarged sectional detail taken on line 4-i of Figure 1.

'.lhroughout the severalwiews similar reference characters will be used for referring to similar parts, and the sections are taken looking in the direction of the small arrows.

Referring to the drawings, my improved shower pipe comprises a pipe 5 having the usual longitudinally spaced openings (i.

"iwo pipes T and 8, respectively, are connected `with the inlet end of shower pipe 5 by means of the T union 9. The first of these pipes is designed to supply steam to the shower pipe and the second is designed fo: supplying water thereto. A valve 10, preferably of the gate type, is inserted in the pipe 7 and a suitable valve 11 provides means for Ycontrolling the fiow of water through the pipe 8. This valve may be of any suitable consti action. rllhe discharge end of the shower pipe is closed by a cap 12 having the valve port 13 termed therein. This port is normally closed by the valve 11iwhich opens inn-*ardly and which is carried by the valve siem 15, which projects outwardly through a bar 16 projecting across the end of the ring 17, which is threaded upon the outer end of the cap 12. A. lever 18 is mounted upon the ring 17 by means of the link 19 and is joined to the outer end of the valve stein 15, at a point intermediate the ends of the lever 18, by means of a pivot 20. One end of a link 21 is pivotally secured to the free end of the lever 18. The opposite end of the link 21 carries a slotted member 22, the slot of which extends in a direction parallel with the link 21. The handle 10 of the gate valve 1() projects through the slot in the member 22 and may move freely therein for the purpose of operating the steam valve 10 without operating the link 21 of the valve 14, but may be rigidly connected with the link by the pin 23, which can be inserted through registering openings in the bifurcations of the member 22 and the handle 10, as shown in Figure 4. I prefer to secure the pin 22 to the link 21 by means of a flexible cable 24, so

that it cannot. become lost. lVhere the shower pipe is comparatively long, I prefer to provide a bracket which is secured to he shower pipe bv means ot screws 26. or in any other desired manner. and which is provided with an eye QT through Which the .link 21 can slide.

lhen the shower pipe is in use. the valves 10 and Ylllare closed and the valve l1 is open. thus pern'littintr water to enter the shoiver pine and he discharged through the openings (i. ldlhen it is 'desired to clean the shower pipe. the handle l is secured to the men'iber b v means ot the pin 23 and then moved to a position to open the valve 10. rlhis movement through the. link 2l simultaueonslv opens the valve 14 and thus permits the steam supplied b v the pipe 7 to pass tlnouvah the shower pipe at high velorrt'v and earrv the dirt ivith it out ot the shoiver pipe. lt desired. the valve ll can at this time he opened to permit ivater to enter the shovver pipe and he mixed Wit-h 'the steanl in the 'i' union and torced through the shower pipe and out through the valve portl 18.

`Dlets otl live steam are treauentlv used' for cleaning drinn molds and the like and the shovver pipe which I have illustrated herein can he used tor that purpose.. in which ease the valve ll will be closed, the handle 10 ivill be disengaged from the member 22. so that the valve let can remain in its closed position. While the valve l0 is open. rlhis ivill pernfiit the desired pipe to he filled With steam under hiejh pressure, and this steam will issue from the opening 6 and impinge upon the drinn mold. thus Cleaning it.

illlhile l have described the details of construction o't the preferred embodiment of niv invention. it is t0 be clearlv understood that inv invention is not limited to these details. hutis capahle ot other adaptations within the scope ot the appended claims.

lflavine thus described in v invention. what l claim is:
